TI中文支持网DSP在线升级，如果改动不大升级完成后工作正常。如果改动比较大DSP连仿真器都连不上了。芯片是28035 。请问可能是什么原因。谢谢！！
升级完成工作不起来，用的是内置晶振。外部没有接晶振。连接仿真器提示：Device may be operating in low-power mode. The debugger has forced the device to wake up. Choose 'OK' to attempt to complete the debug connection.
Seven Han：Low power run mode
These errors mean the device is in low power run mode. Depending on the severity of the condition, the JTAG debugger may or may not be able to bring it out of this mode.
If there are no other external factors that are holding this device in low power, the JTAG debugger will most probably be able to successfully bring the device out of this mode:
